Kolkata flyover collapse: Video captures moment under-construction bridge crashes on to road

Shocking CCTV video footage has been released showing the moment an under-construction flyover bridge in the Indian city Kolkata collapsed, killing at least 17 people and injured 78 others.

The dramatic footage shows the flyover bridge suddenly crashing down on to the people and vehicles on the street below on 31 March. More than 150 are feared to be trapped by the collapse of Vivekananda Flyover in the northern part of the city, near Kolkata's Girish Park area.

The flyover had been under construction since 2009 and had repeatedly missed deadlines for completion, with many saying that lack of inspections and the use of inadequate materials had led to its failure.
